Constructor Detail

Field

public Field(Field c)
Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.

Field

public Field(int access_flags, int name_index, int signature_index, Attribute[] attributes, ConstantPool constant_pool)

Parameters: access_flags Access rights of field name_index Points to field name in constant pool signature_index Points to encoded signature attributes Collection of attributes constant_pool Array of constants

Method Detail

accept

public void accept(Visitor v)
Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Parameters: v Visitor object

copy

public final Field copy(ConstantPool _constant_pool)

Returns: deep copy of this field

equals

public boolean equals(Object obj)
Return value as defined by given BCELComparator strategy. By default two Field objects are said to be equal when their names and signatures are equal.

See Also: java.lang.Object#equals(java.lang.Object)

getComparator

public static BCELComparator getComparator()

Returns: Comparison strategy object

getConstantValue

public final ConstantValue getConstantValue()

Returns: constant value associated with this field (may be null)

getType

public Type getType()

Returns: type of field

hashCode

public int hashCode()
Return value as defined by given BCELComparator strategy. By default return the hashcode of the field's name XOR signature.

See Also: java.lang.Object#hashCode()

setComparator

public static void setComparator(BCELComparator comparator)

Parameters: comparator Comparison strategy object

toString

public final String toString()
Return string representation close to declaration format, `public static final short MAX = 100', e.g..

Returns: String representation of field, including the signature.
