Libraries.Language.Compile.Translate.JavaBytecodeOpcodes Documentation

This class represents raw bytecode constants taken from the ASM 5 java bytecode library. What little documentation exists for them can be found here: http://asm.ow2.org/asm50/javadoc/user/org/objectweb/asm/Opcodes.html#V1_8 In the future, this constants should be changed to make more sense in English. In the meantime, they are private and intentionally match ASM. Public actions giving values back should use more realistic English phrases.

Inherits from: Libraries.Language.Object

Actions Documentation

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

ConvertTypeToBytecodeLoadOpcode(Libraries.Language.Compile.Symbol.Type type)

Parameters

Return

integer

ConvertTypeToBytecodeStoreOpcode(Libraries.Language.Compile.Symbol.Type type)

Parameters

Return

integer

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
