Method Detail

kind

public CelKind kind()

Description copied from class: CelType

Return the type CelKind.

Specified by:

kind in class CelType

name

public java.lang.String name()

Description copied from class: CelType

Return the type name.

For struct types this should be the fully qualified name. Be wary of introducing unqualified type names as they may collide with future CEL type.

Specified by:

name in class CelType

isAssignableFrom

public boolean isAssignableFrom(CelType other)

Description copied from class: CelType

Determine whether this type is assignable from the other type value.

Defaults to an equality test.

Overrides:

isAssignableFrom in class CelType

findNumberByName

public java.util.Optional<java.lang.Integer> findNumberByName(java.lang.String enumName)

Find an enum number by enumName.

findNameByNumber

public java.util.Optional<java.lang.String> findNameByNumber(java.lang.Integer enumNumber)

Find an enum name by enumNumber.
