Method Detail

fromCheckedExpr

public static CelProtoAbstractSyntaxTree fromCheckedExpr(CheckedExpr checkedExpr)

Construct an abstract syntax tree from a CheckedExpr.

fromParsedExpr

public static CelProtoAbstractSyntaxTree fromParsedExpr(ParsedExpr parsedExpr)

Construct an abstract syntax tree from a ParsedExpr.

fromCelAst

public static CelProtoAbstractSyntaxTree fromCelAst(CelAbstractSyntaxTree ast)

Constructs CelProtoAbstractSyntaxTree from CelAbstractSyntaxTree.

isChecked

public boolean isChecked()

Tests whether the underlying abstract syntax tree has been type checked or not.

getAst

@CheckReturnValue
public CelAbstractSyntaxTree getAst()

Returns the native representation of the abstract syntax tree: CelAbstractSyntaxTree.

getExpr

@CheckReturnValue
public Expr getExpr()

Returns the underlying Expr representation of the abstract syntax tree.

toCheckedExpr

@CheckReturnValue
public CheckedExpr toCheckedExpr()

Returns the underlying CheckedExpr representation of the abstract syntax tree. Throws IllegalStateException if CelAbstractSyntaxTree.isChecked() is false.

getSourceInfo

@CheckReturnValue
public SourceInfo getSourceInfo()

Returns the underlying SourceInfo representation of the abstract syntax tree.

toParsedExpr

@CheckReturnValue
public ParsedExpr toParsedExpr()

Returns the underlying ParsedExpr representation of the abstract syntax tree.

getProtoResultType

@CheckReturnValue
public Type getProtoResultType()

For a type checked abstract syntax tree the resulting type is returned in proto format described in checked.proto. Otherwise, the dynamic type is returned.
