Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

typeName

public String typeName()

Returns the human-readable name corresponding to this type.

Returns:

the human-readable name corresponding to this type

descriptor

public String descriptor()

Returns the field descriptor character corresponding to this type.

Returns:

the field descriptor character corresponding to this type

newarraycode

public int newarraycode()

Returns:

the number of local variable slots consumed by this type

asLoadable

public TypeKind asLoadable()

Erase this type kind to the type which will be used for xLOAD, xSTORE, and xRETURN bytecodes

Returns:

the erased type kind

fromNewArrayCode

public static TypeKind fromNewArrayCode(int newarraycode)

Returns the type kind associated with the array type described by the array code used as an operand to newarray.
