java.lang.Object

com.fasterxml.jackson.databind.introspect.AccessorNamingStrategy.Provider

com.fasterxml.jackson.databind.introspect.DefaultAccessorNamingStrategy.Provider

All Implemented Interfaces:

Serializable

Enclosing class:

DefaultAccessorNamingStrategy

public static class DefaultAccessorNamingStrategy.Provider
extends AccessorNamingStrategy.Provider
implements Serializable

Provider for DefaultAccessorNamingStrategy.

Default instance will use following default prefixes:

• Setter for regular POJOs: "set"
• Builder-mutator: "with"
• Regular getter: "get"
• Is-getter (for Boolean values): "is"

and no additional restrictions on base names accepted (configurable for limits using DefaultAccessorNamingStrategy.BaseNameValidator), allowing names like "get_value()" and "getvalue()".

Method Summary

Modifier and Type	Method and Description
AccessorNamingStrategy	forBuilder(MapperConfig<?> config, AnnotatedClass builderClass, BeanDescription valueTypeDesc) Factory method for creating strategy instance for POJOs that are deserialized using Builder type: in this case eventual target (value) type is different from type of "builder" object that is used by databinding to accumulate state.
AccessorNamingStrategy	forPOJO(MapperConfig<?> config, AnnotatedClass targetClass) Factory method for creating strategy instance for a "regular" POJO, called if none of the other factory methods is applicable.
AccessorNamingStrategy	forRecord(MapperConfig<?> config, AnnotatedClass recordClass) Factory method for creating strategy instance for special java.lang.Record type (new in JDK 14).
DefaultAccessorNamingStrategy.Provider	withBaseNameValidator(DefaultAccessorNamingStrategy.BaseNameValidator vld) Mutant factory for specifying validator that is used to further verify that base name derived from accessor name is acceptable: this can be used to add further restrictions such as limit that the first character of the base name is an upper-case letter.
DefaultAccessorNamingStrategy.Provider	withBuilderPrefix(String prefix) Mutant factory for changing the prefix used for Builders (from default JsonPOJOBuilder.DEFAULT_WITH_PREFIX)
DefaultAccessorNamingStrategy.Provider	withFirstCharAcceptance(boolean allowLowerCaseFirstChar, boolean allowNonLetterFirstChar) Mutant factory for changing the rules regarding which characters are allowed as the first character of property base name, after checking and removing prefix.
DefaultAccessorNamingStrategy.Provider	withGetterPrefix(String prefix) Mutant factory for changing the prefix used for "getter" methods
DefaultAccessorNamingStrategy.Provider	withIsGetterPrefix(String prefix) Mutant factory for changing the prefix used for "is-getter" methods (getters that return boolean/Boolean value).
DefaultAccessorNamingStrategy.Provider	withSetterPrefix(String prefix) Mutant factory for changing the prefix used for "setter" methods

Method Detail

withSetterPrefix

public DefaultAccessorNamingStrategy.Provider withSetterPrefix(String prefix)

Mutant factory for changing the prefix used for "setter" methods

Parameters:

prefix - Prefix to use; or empty String "" to not use any prefix (meaning signature-compatible method name is used as the property basename (and subject to name mangling)), or null to prevent name-based detection.

Returns:

Provider instance with specified setter-prefix

withBuilderPrefix

public DefaultAccessorNamingStrategy.Provider withBuilderPrefix(String prefix)

Mutant factory for changing the prefix used for Builders (from default JsonPOJOBuilder.DEFAULT_WITH_PREFIX)

Parameters:

prefix - Prefix to use; or empty String "" to not use any prefix (meaning signature-compatible method name is used as the property basename (and subject to name mangling)), or null to prevent name-based detection.

Returns:

Provider instance with specified with-prefix

withGetterPrefix

public DefaultAccessorNamingStrategy.Provider withGetterPrefix(String prefix)

Mutant factory for changing the prefix used for "getter" methods

Parameters:

prefix - Prefix to use; or empty String "" to not use any prefix (meaning signature-compatible method name is used as the property basename (and subject to name mangling)), or null to prevent name-based detection.

Returns:

Provider instance with specified getter-prefix

withIsGetterPrefix

public DefaultAccessorNamingStrategy.Provider withIsGetterPrefix(String prefix)

Mutant factory for changing the prefix used for "is-getter" methods (getters that return boolean/Boolean value).

Parameters:

prefix - Prefix to use; or empty String "" to not use any prefix (meaning signature-compatible method name is used as the property basename (and subject to name mangling)). or null to prevent name-based detection.

Returns:

Provider instance with specified is-getter-prefix

withFirstCharAcceptance

public DefaultAccessorNamingStrategy.Provider withFirstCharAcceptance(boolean allowLowerCaseFirstChar,
                                                                      boolean allowNonLetterFirstChar)

Mutant factory for changing the rules regarding which characters are allowed as the first character of property base name, after checking and removing prefix.

For example, consider "getter" method candidate (no arguments, has return type) named getValue() is considered, with "getter-prefix" defined as get, then base name is Value and the first character to consider is V. Upper-case letters are always accepted so this is fine. But with similar settings, method get_value() would only be recognized as getter if allowNonLetterFirstChar is set to true: otherwise it will not be considered a getter-method. Similarly "is-getter" candidate method with name island() would only be considered if allowLowerCaseFirstChar is set to true.

Parameters:

allowLowerCaseFirstChar - Whether base names that start with lower-case letter (like "a" or "b") are accepted as valid or not: consider difference between "setter-methods" setValue() and setvalue().

allowNonLetterFirstChar - Whether base names that start with non-letter character (like "_" or number 1) are accepted as valid or not: consider difference between "setter-methods" setValue() and set_value().

Returns:

Provider instance with specified validity rules

withBaseNameValidator

public DefaultAccessorNamingStrategy.Provider withBaseNameValidator(DefaultAccessorNamingStrategy.BaseNameValidator vld)

Mutant factory for specifying validator that is used to further verify that base name derived from accessor name is acceptable: this can be used to add further restrictions such as limit that the first character of the base name is an upper-case letter.

Parameters:

vld - Validator to use, if any; null to indicate no additional rules

Returns:

Provider instance with specified base name validator to use, if any
