Class CelConstant

java.lang.Object

dev.cel.common.ast.CelConstant

@Internal
@Immutable
public abstract class CelConstant
extends java.lang.Object

notSet

public abstract CelConstant.CelConstantNotSet notSet()

nullValue

public abstract com.google.protobuf.NullValue nullValue()

booleanValue

public abstract boolean booleanValue()

bytesValue

public abstract com.google.protobuf.ByteString bytesValue()

timestampValue

@Deprecated
public abstract com.google.protobuf.Timestamp timestampValue()

Deprecated.

Do not use. Timestamp is no longer built-in CEL type.

durationValue

@Deprecated
public abstract com.google.protobuf.Duration durationValue()

Deprecated.

Do not use. Duration is no longer built-in CEL type.

ofNotSet

public static CelConstant ofNotSet()

ofValue

public static CelConstant ofValue(com.google.protobuf.NullValue value)

ofValue

public static CelConstant ofValue(boolean value)

ofValue

public static CelConstant ofValue(long value)

ofValue

public static CelConstant ofValue(com.google.common.primitives.UnsignedLong value)

ofValue

public static CelConstant ofValue(double value)

ofValue

public static CelConstant ofValue(java.lang.String value)

ofValue

public static CelConstant ofValue(com.google.protobuf.ByteString value)

isConstantValue

public static boolean isConstantValue(java.lang.Object value)

Checks whether the provided Java object is a valid CelConstant value.

ofObjectValue

public static CelConstant ofObjectValue(java.lang.Object value)

Converts the given Java object into a CelConstant value. This is equivalent of calling ofValue(com.google.protobuf.NullValue) with concrete types.

Throws:

java.lang.IllegalArgumentException - If the value is not a supported CelConstant. This includes the deprecated duration and timestamp values.

ofValue

@Deprecated
public static CelConstant ofValue(com.google.protobuf.Duration value)

Deprecated.

Do not use. Duration is no longer built-in CEL type.

ofValue

@Deprecated
public static CelConstant ofValue(com.google.protobuf.Timestamp value)

Deprecated.

Do not use. Timestamp is no longer built-in CEL type.
