protected Bytecodes.FieldInstruction(short opcode,
                                     jq_Field f)

Parameters:

opcode - instruction opcode

f - field

Method Detail

toString

public String toString()

Overrides:

toString in class Bytecodes.CPInstruction

Returns:

mnemonic for instruction with symbolic references resolved

getField

public jq_Field getField()

getFieldSize

protected int getFieldSize()

Returns:

size of field (1 or 2)

getType

public jq_Type getType()

Description copied from interface: Bytecodes.LoadClass

Returns the type associated with this instruction. LoadClass instances are always typed, but this type does not always refer to the type of the class or interface that it possibly forces to load. For example, GETFIELD would return the type of the field and not the type of the class where the field is defined. If no class is forced to be loaded, null is returned. An example for this is an ANEWARRAY instruction that creates an int[][].

Specified by:

getType in interface Bytecodes.LoadClass

Specified by:

getType in interface Bytecodes.TypedInstruction

Overrides:

getType in class Bytecodes.CPInstruction

Returns:

return type of referenced field

Bytecodes.LoadClass.getLoadClassType()

getFieldType

public jq_Type getFieldType()

Returns:

type of field

getFieldName

public String getFieldName()

Returns:

name of referenced field.
