CalculateBytecodeOffset(Libraries.Language.Compile.Symbol.Variable variable)

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)

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)

Evaluate(Libraries.Language.Compile.Interpreter.Runtime runtime)

Some opcodes can be evaluated in the context of a runtime environment

Parameters

GetBytecodeOffset()

Return

integer

GetCheckLabelInteger()

Return

integer

GetErrorDetectBlock()

If this check detect block has a catch-all Error block, for any kind of error that is thrown.

Return

Libraries.Language.Compile.Translate.DetectBlockOpcode:

GetHashCode()

This action gets the hash code for an object.

Return

integer: The integer hash code of the object.

Example

Object o
integer hash = o:GetHashCode()

GetIsIfExpression()

Return

boolean

GetTemplateCopy()

if the block is empty, there's no need to write detect blocks

Return

Libraries.Language.Compile.Translate.QuorumOpcode:

HasDetectBlockType(text type)

Parameters

  • text type

Return

boolean

HasErrorDetectBlock()

Sets the error detection catch all block to a particular detect block. This block contains the class Error somewhere in its iterator.

Return

boolean:

SetAlwaysBlock(Libraries.Language.Compile.Translate.DetectBlockOpcode block)

SetBlock(Libraries.Language.Compile.Translate.BlockOpcode block)

SetBytecodeWriteOffset(integer offset)

Parameters

  • integer offset

SetBytecodeWriteOffsetToAllChildren(integer offset)

If this check detect block has a catch-all Error block, for any kind of error that is thrown.

Parameters

  • integer offset

SetCheckLabelInteger(integer value)

Parameters

  • integer value

SetErrorClass(Libraries.Language.Compile.Symbol.Class clazz)

SetErrorDetectBlock(Libraries.Language.Compile.Translate.DetectBlockOpcode block)

Sets the error detection catch all block to a particular detect block. This block contains the class Error somewhere in its iterator.

Parameters
