net.bytebuddy.implementation.Implementation.Context.Default.FieldCacheEntry

All Implemented Interfaces:

StackManipulation

Enclosing class:

Implementation.Context.Default

protected static class Implementation.Context.Default.FieldCacheEntry
extends java.lang.Object
implements StackManipulation

A field cache entry for uniquely identifying a cached field. A cached field is described by the stack manipulation that loads the field's value onto the operand stack and the type of the field.

Constructor Detail

FieldCacheEntry

protected FieldCacheEntry(StackManipulation fieldValue,
                          TypeDescription fieldType)

Creates a new field cache entry.

Parameters:

fieldValue - The field value that is represented by this field cache entry.

fieldType - The field type that is represented by this field cache entry.

Method Detail

storeIn

protected ByteCodeAppender storeIn(FieldDescription fieldDescription)

Returns a stack manipulation where the represented value is stored in the given field.

Parameters:

fieldDescription - A static field in which the value is to be stored.

Returns:

A byte code appender that represents this storage.

getFieldType

protected TypeDescription getFieldType()

Returns the field type that is represented by this field cache entry.

Returns:

The field type that is represented by this field cache entry.

isValid

public boolean isValid()

Determines if this stack manipulation is valid.

Specified by:

isValid in interface StackManipulation

Returns:

If false, this manipulation cannot be applied and should throw an exception.

apply

public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
                                    Implementation.Context implementationContext)

Applies the stack manipulation that is described by this instance.

Specified by:

apply in interface StackManipulation

Parameters:

methodVisitor - The method visitor used to write the method implementation to.

implementationContext - The context of the current implementation.

Returns:

The changes to the size of the operand stack that are implied by this stack manipulation.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object
