Constructor Detail

ToStringMethod

protected ToStringMethod(ToStringMethod.PrefixResolver prefixResolver)

Creates a new toString implementation.

Parameters:

prefixResolver - A resolver for the prefix of a String representation.

Method Detail

prefixedByFullyQualifiedClassName

public static ToStringMethod prefixedByFullyQualifiedClassName()

Creates a Object.toString() implementation that is prefixed by the fully qualified class name of the instrumented type.

Returns:

A Object.toString() implementation that is prefixed by the fully qualified class name of the instrumented type.

prefixedByCanonicalClassName

public static ToStringMethod prefixedByCanonicalClassName()

Creates a Object.toString() implementation that is prefixed by the canonical class name of the instrumented type.

Returns:

A Object.toString() implementation that is prefixed by the canonical class name of the instrumented type.

prefixedBySimpleClassName

public static ToStringMethod prefixedBySimpleClassName()

Creates a Object.toString() implementation that is prefixed by the simple class name of the instrumented type.

Returns:

A Object.toString() implementation that is prefixed by the simple class name of the instrumented type.

prefixedBy

public static ToStringMethod prefixedBy(java.lang.String prefix)

Creates a Object.toString() implementation that is prefixed by the supplied string.

Parameters:

prefix - The prefix to use.

Returns:

A Object.toString() implementation that is prefixed by the supplied string.

prefixedBy

public static ToStringMethod prefixedBy(ToStringMethod.PrefixResolver prefixResolver)

Creates a Object.toString() implementation that is prefixed by the string that is supplied by the given prefix resolver.

Parameters:

prefixResolver - The prefix resolver to use.

Returns:

A Object.toString() implementation that is prefixed by the string that is supplied by the given prefix resolver.

withIgnoredFields

public ToStringMethod withIgnoredFields(ElementMatcher<? super FieldDescription.InDefinedShape> ignored)

Returns a new version of this toString method implementation that ignores the specified fields additionally to any previously specified fields.

Parameters:

ignored - A matcher to specify any fields that should be ignored.

Returns:

A new version of this toString method implementation that also ignores any fields matched by the provided matcher.

withTokens

public Implementation withTokens(java.lang.String start,
                                 java.lang.String end,
                                 java.lang.String separator,
                                 java.lang.String definer)

Changes the tokens used for the Object.toString() implementation.

Parameters:

start - A token that is added between the prefix and the first field value.

end - A token that is added after the last field value.

separator - A token that is added between two field values.

definer - A token that is added between two field values.

Returns:

A new instance of this implementation that uses the supplied tokens.

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Description copied from interface: InstrumentedType.Prepareable

Prepares a given instrumented type.

Specified by:

prepare in interface InstrumentedType.Prepareable

Parameters:

instrumentedType - The instrumented type in its current form.

Returns:

The prepared instrumented type.

appender

public ToStringMethod.Appender appender(Implementation.Target implementationTarget)

Description copied from interface: Implementation

Creates a byte code appender that determines the implementation of the instrumented type's methods.

Specified by:

appender in interface Implementation

Parameters:

implementationTarget - The target of the current implementation.

Returns:

A byte code appender for implementing methods delegated to this implementation. This byte code appender is also responsible for handling methods that were added by this implementation on the call to InstrumentedType.Prepareable.prepare(InstrumentedType).
