Method Detail

setOptions

public CelCompilerBuilder setOptions(CelOptions options)

Description copied from interface: CelCompilerBuilder

Set the CelOptions used to enable fixes and features for this CEL instances.

Specified by:

setOptions in interface CelCompilerBuilder

setStandardMacros

public CelCompilerBuilder setStandardMacros(CelStandardMacro... macros)

Description copied from interface: CelCompilerBuilder

Sets the macro set for the parser, replacing the macros from any prior call.

Specified by:

setStandardMacros in interface CelCompilerBuilder

setStandardMacros

public CelCompilerBuilder setStandardMacros(java.lang.Iterable<CelStandardMacro> macros)

Description copied from interface: CelCompilerBuilder

Sets the macro set for the parser, replacing the macros from any prior call.

Specified by:

setStandardMacros in interface CelCompilerBuilder

addMacros

public CelCompilerBuilder addMacros(CelMacro... macros)

Description copied from interface: CelCompilerBuilder

Registers the given macros, replacing any previous macros with the same key.

Use this to register a set of user-defined custom macro implementation for the parser. For registering macros defined as part of CEL standard library, use CelCompilerBuilder.setStandardMacros(dev.cel.parser.CelStandardMacro...) instead.

Custom macros should not use the same function names as the ones found in CelStandardMacro (ex: has, all, exists, etc.). Build method will throw if both standard macros and custom macros are set with the same name.

Specified by:

addMacros in interface CelCompilerBuilder

addMacros

public CelCompilerBuilder addMacros(java.lang.Iterable<CelMacro> macros)

Description copied from interface: CelCompilerBuilder

Registers the given macros, replacing any previous macros with the same key.

Use this to register a set of user-defined custom macro implementation for the parser. For registering macros defined as part of CEL standard library, use CelCompilerBuilder.setStandardMacros(dev.cel.parser.CelStandardMacro...) instead.

Custom macros should not use the same function names as the ones found in CelStandardMacro (ex: has, all, exists, etc.). Build method will throw if both standard macros and custom macros are set with the same name.

Specified by:

addMacros in interface CelCompilerBuilder

Description copied from interface: CelCompilerBuilder

Set the container name to use as the namespace for resolving CEL expression variables and functions.

Specified by:

setContainer in interface CelCompilerBuilder

addProtoTypeMasks

public CelCompilerBuilder addProtoTypeMasks(ProtoTypeMask... typeMasks)

Description copied from interface: CelCompilerBuilder

Add one or more ProtoTypeMask values. The ProtoTypeMask values will be used to compute a set of Decl values using a protobuf message's fields as the names and types of the variables if ProtoTypeMask.fieldsAreVariableDeclarations() is true.

Note, this feature may not work with custom TypeProvider implementations out of the box, as it requires the implementation of TypeProvider#lookupFieldNames to return the set of all fields declared on the protobuf type.

Specified by:
