Class CelMacroExprFactory

java.lang.Object

dev.cel.common.ast.CelExprFactory

dev.cel.parser.CelMacroExprFactory

public abstract class CelMacroExprFactory
extends CelExprFactory

Assists with the expansion of CelMacro in a manner which is consistent with the source position and expression ID generation code leveraged by both the parser and type-checker.

Method Detail

reportError

@FormatMethod
public final CelExpr reportError(@FormatString
                                 java.lang.String format,
                                 java.lang.Object... args)

Creates a CelIssue and reports it, returning a sentinel CelExpr that indicates an error.

reportError

public final CelExpr reportError(java.lang.String message)

Creates a CelIssue and reports it, returning a sentinel CelExpr that indicates an error.

reportError

public abstract CelExpr reportError(CelIssue error)

Reports a CelIssue and returns a sentinel CelExpr that indicates an error.

getAccumulatorVarName

public abstract java.lang.String getAccumulatorVarName()

Returns the default accumulator variable name used by macros implementing comprehensions.

getSourceLocation

public final CelSourceLocation getSourceLocation(CelExpr expr)

Retrieves the source location for the given CelExpr ID.

copy

public final CelExpr copy(CelExpr expr)

Duplicates CelExpr with a brand new set of identifiers.

copyExprId

protected abstract long copyExprId(long id)

Returns the next unique expression ID which is associated with the same metadata (i.e. source location, types, references, etc.) as `id`.

getSourceLocation

protected abstract CelSourceLocation getSourceLocation(long exprId)

Retrieves the source location for the given CelExpr ID.

currentSourceLocationForMacro

protected abstract CelSourceLocation currentSourceLocationForMacro()

Returns the current (last known) source location. This should only be used for macros.
