Libraries.Language.Compile.Symbol.Block

This action returns all variables in this, and only this, block. Variables in parent scope or child scope are excluded.

Sets whether this block has a return value. This value is set during the parsing phase and should not be adjusted afterward.

Determines whether this block has a return value. This value is set during the parsing phase.

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.

Example Code

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

This action determines whether this block has a valid return statement at some point within it. If this block does have a return, it checks its subblocks. If all of its subblocks have a return, this action returns true as well. Note that the semantics of this action require separate processing in the semantic analysis layer before it can compute the correct value. The reason is because any given subblock may be within some structure, like an if statement, loop, or the like, and these statements can choose has they define satisfaction of a return in any mathematically sensible way they choose, according to their meaning.

This action is a helper action to get copies of the location.

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

Example Code

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

Returns the number of blocks that are contained within this block at the root level. Blocks inside of this block may contain their own sub-blocks, but these are not counted by this action.

This action computes whether or not a variable of the same name exists in this block or one of its parents. If it does, it returns true, otherwise false.

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

Returns the number of blocks that are contained within this block at the root level. Blocks inside of this block may contain their own sub-blocks, but these are not counted by this action.

This action returns all variables in this, and only this, block. Variables in parent scope or child scope are excluded.

This action gets all variables in this block and all parents

Determines whether an error has already been issued from this block from statements that cannot be executed. An example of this would issuing a return now from an action then trying to assign to a variable.

Determines whether this block has a return value. This value is set during the parsing phase.

This action computes whether or not a variable of the same name exists in this block or one of its parents. If it does, it returns true, otherwise false.

if undefined, check the paren

Sets whether an error has already been issued from this block from statements that cannot be executed. An example of this would issuing a return now from an action then trying to assign to a variable.

This action uses the location and resets the current error's data.

not a parameter either, so check the class's fiel

if undefined, check the paren

Sets whether this block has a return value. This value is set during the parsing phase and should not be adjusted afterward.

This action is a helper action to get copies of the location.
