Constructor Detail

AccessorInfo

public AccessorInfo(MixinTargetContext mixin,
                    org.objectweb.asm.tree.MethodNode method)

AccessorInfo

protected AccessorInfo(MixinTargetContext mixin,
                       org.objectweb.asm.tree.MethodNode method,
                       java.lang.Class<? extends java.lang.annotation.Annotation> annotationClass)

Method Detail

initType

protected AccessorInfo.AccessorType initType()

initTargetFieldType

protected org.objectweb.asm.Type initTargetFieldType()

initTarget

protected ITargetSelector initTarget()

getTargetName

protected java.lang.String getTargetName(java.lang.String name)

inflectTarget

protected java.lang.String inflectTarget()

Uses the name of this accessor method and the calculated accessor type to try and inflect the name of the target field or method. This allows a method named getFoo to be inflected to a target named foo for example.

inflectTarget

public static java.lang.String inflectTarget(java.lang.String name,
                                             AccessorInfo.AccessorType type,
                                             java.lang.String description,
                                             IMixinContext context,
                                             boolean verbose)

Uses the name of an accessor method and the accessor type to try and inflect the name of the target field or method. This allows a method named getFoo to be inflected to a target named foo for example.

Parameters:

name - Name of the accessor method

type - Type of accessor being processed, this is calculated from the method signature (void methods being setters, methods with return types being getters)

description - description of the accessor to include in error messages

context - Mixin context

verbose - Emit warnings when accessor prefix doesn't match type

Returns:

inflected target member name or null if name cannot be inflected

inflectTarget

public static java.lang.String inflectTarget(AccessorInfo.AccessorName name,
                                             AccessorInfo.AccessorType type,
                                             java.lang.String description,
                                             IMixinContext context,
                                             boolean verbose)

Uses the name of an accessor method and the accessor type to try and inflect the name of the target field or method. This allows a method named getFoo to be inflected to a target named foo for example.

Parameters:

name - Name of the accessor method

type - Type of accessor being processed, this is calculated from the method signature (void methods being setters, methods with return types being getters)

description - description of the accessor to include in error messages

context - Mixin context

verbose - Emit warnings when accessor prefix doesn't match type

Returns:

inflected target member name or null if name cannot be inflected

getTarget

public final ITargetSelector getTarget()

Get the inflected/specified target member for this accessor

getTargetFieldType

public final org.objectweb.asm.Type getTargetFieldType()

For field accessors, returns the field type, returns null for invokers

getTargetField

public final org.objectweb.asm.tree.FieldNode getTargetField()

For field accessors, returns the target field, returns null for invokers

getTargetMethod

public final org.objectweb.asm.tree.MethodNode getTargetMethod()

For invokers, returns the target method, returns null for field accessors

getReturnType

public final org.objectweb.asm.Type getReturnType()

Get the return type of the annotated method

getArgTypes

public final org.objectweb.asm.Type[] getArgTypes()

Get the argument types of the annotated method

isStatic

public boolean isStatic()

Get whether the accessor itself is static

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

locate

public void locate()

First pass, locate the target field in the class. This is done after all other mixins are applied so that mixin-added fields and methods can be targetted.

generate

public org.objectweb.asm.tree.MethodNode generate()

Second pass, generate the actual accessor method for this accessor. The method still respects intrinsic/mixinmerged rules so is not guaranteed to be added to the target class

Returns:

generated accessor method

findTarget

protected <TNode> TNode findTarget(java.util.List<ElementNode<TNode>> nodes)

Generified candidate search, since the search logic is the same for both fields and methods.

Type Parameters:

TNode - node type

Parameters:

nodes - Node list to search (method/field list)

Returns:

best match

of

public static AccessorInfo of(MixinTargetContext mixin,
                              org.objectweb.asm.tree.MethodNode method,
                              java.lang.Class<? extends java.lang.annotation.Annotation> type)

Return a wrapper AccessorInfo of the correct type based on the method passed in.

Parameters:

mixin - mixin context which owns this accessor

method - annotated method

type - annotation type to process

Returns:

parsed AccessorInfo
