Class Summary

Class	Description
AbbreviatePositionalValues	Check shorthand rule declarations that define positional values, such as padding and margin, and eliminate duplicate values if possible.
AutoExpandBrowserPrefix	A compiler pass that automatically detects certain properties that need additional browser specific property declarations, and adds them.
BiDiFlipper	Compiler pass that BiDi flips all the flippable nodes.
BooleanExpressionEvaluator	An evaluator for boolean expressions.
BrowserPrefixGenerator	A utility for the AutoExpandBrowserPrefix pass, which provides a list of rules that govern automatic addition of browser specific property declarations.
BrowserPrefixRule	A utility for the AutoExpandBrowserPrefix pass, which provides a list of rules that govern automatic addition of browser specific property declarations.
CheckDependencyNodes	CheckDependencyNodes ensures that @provide nodes appear before @require nodes.
CheckMissingRequire	A compiler pass that checks for missing @require lines for def constant references and mixins.
CodeBuffer	Class to write/delete characters used by CodePrinter subclasses to print out code.

CollectProvideNamespaces	A compiler pass to help find missing @require lines for def constant references and mixins.
ColorValueOptimizer	Compiler pass that optimizes color values.
CompactPrinter	A compact-printer for CssTree instances.
CompactPrintingVisitor	A compact-printer for CssTree instances.
ConstantDefinitions	A container for GSS constant definitions, since a constant could be defined multiple times in the tree, this class has two set of interfaces that can be used to get either all definitions of a constant or only last definition of a constant.
CreateComponentNodes	A compiler pass that transforms each well-formed @component or @abstract_component CssUnknownAtRuleNode into a CssComponentNode.
CreateConditionalNodes	A compiler pass that replaces each @if, @elseif, and @else CssUnknownAtRuleNode with appropriate conditional nodes (CssConditionalBlockNode and CssConditionalRuleNode).
CreateConstantReferences	A compiler pass that transforms each upper-cased CssLiteralNode to a CssConstantReferenceNode.
CreateDefinitionNodes	A compiler pass that transforms each well-formed @def CssUnknownAtRuleNode to a CssDefinitionNode.
CreateForLoopNodes	A compiler pass that replaces each @for with a CssForLoopRuleNode.
CreateMixins	A compiler pass that transforms matching CssUnknownAtRuleNode instances into mixins or mixin definitions.
CreateStandardAtRuleNodes	A compiler pass that transforms standard CssUnknownAtRuleNode instances to more specific at-rule nodes, or deletes them.
CreateVendorPrefixedKeyframes	Compiler pass which duplicates @keyframes rules creating browser specific prefixed form.
CssClassRenaming	Compiler pass that does CSS class renaming given a renaming map.
DefaultGssSourceMapGenerator	Class to collect and generate source map(v3) for Gss compiler.
DefinitionPrintingVisitor<T>	Printer for definition nodes, which outputs GSS definitions so that they can be re-parsed later.
DelegatingVisitor	Dispatches to multiple CssTreeVisitors.
DisallowDuplicateDeclarations	Compiler pass that reports an error if a ruleset has two of the same declarations that are not marked as alternate.
DummyErrorManager	DummyErrorManager is a stateless error manager suitable for use in the Null Object pattern.
EliminateConditionalNodes	A compiler pass that eliminates the conditional blocks for which the boolean expression does not evaluate to true.
EliminateEmptyRulesetNodes	A compiler pass that eliminates the empty ruleset nodes.
EliminateUnitsFromZeroNumericValues	A compiler pass that eliminates useless units from 0.
EliminateUselessRulesetNodes	Compiler pass that removes useless ruleset nodes from the AST.
EnumeratingVisitor	A visitor that maps nodes to their visit ordering.
EvaluateCompileConstants	Evaluates integer constants provided typically through command line.
FixupFontDeclarations	Compiler pass that replaces font and font-family declaration subtrees so that the tree structure resembles the (rather idiosyncratic) grammar of the corresponding CSS properties.
HandleMissingConstantDefinitions	Compiler pass that throws an error for any CssConstantReferenceNode that do not have a corresponding CssDefinitionNode.
HandleUnknownAtRuleNodes	Compiler pass that handles remaining CssUnknownAtRuleNode instances by optionally reporting them as errors and optionally removing them.
HasConditionalNodes
LocationBoundingVisitor	A pass for finding an approximation to a minimum-size SourceCodeLocation interval that contains a given node.
MapChunkAwareNodesToChunk<T>	Pass which marks which ChunkAware nodes belong to which chunk.
MarkDefaultDefinitions	Compiler pass that traverses the tree and marks as default the value nodes in a definition that has the corresponding annotation.
MarkNonFlippableNodes	Compiler pass that traverses the tree and marks as non flippable the nodes that should not be BiDi flipped.
MarkRemovableRulesetNodes	Compiler pass that marks the ruleset nodes that should be removed from the tree.
MarkRemovableRulesetNodesForChunk<T>	Compiler pass that marks ruleset nodes that should be removed from the tree, within the confines of a single chunk.
MergeAdjacentRulesetNodesWithSameDeclarations	Compiler pass that merges adjacent ruleset nodes that have the same selector.
MergeAdjacentRulesetNodesWithSameSelector	Compiler pass that merges adjacent ruleset nodes that have the same selector.
NullGssSourceMapGenerator	Null class implements GssSourceMapGenerator.
PassRunner	PassRunner runs applies a sequence of CssCompilerPasses to a CssTree.
PassUtil	Utility methods that can be useful for compiler passes.
PrettyPrinter	A pretty-printer for CssTree instances.
PrettyPrintingVisitor	A pretty-printer for CssTree instances.
ProcessComponents<T>
ProcessKeyframes	Compiler pass which ensures that @keyframes rules are only allowed if they are enabled.
ProcessRefiners	Compiler pass which ensures that refiners are correctly formated because not every invalid format is rejected by the parser.
RemoveDefaultDeclarations	Compiler pass that removes declaration nodes that have all the property values marked as default.
RemoveEmptyValues	Compiler pass that removes empty values and their containing declaration nodes if they become empty.
RemoveVendorSpecificProperties	A CssCompilerPass that removes all vendor-specific properties, except for one Vendor that is specified in the constructor.
ReplaceConstantReferences	Compiler pass that replaces the constant references with the right values.
ReplaceMixins	Compiler pass that replaces mixins with the corresponding mixin definitions and replaces the variables in the definitions with the values given by the mixin.
ResolveCustomFunctionNodes	This compiler pass replaces CssCustomFunctionNode instances with the list of nodes returned by the GssFunction.
ResolveCustomFunctionNodesForChunks<T>	This compiler pass evaluates CssCustomFunctionNode instances only when they have no references as arguments.
SExprPrinter	Build up an s-expression corresponding to the AST for debugging purposes.
SExprPrintingVisitor	Build up an s-expression corresponding to the AST for debugging purposes.
SplitRulesetNodes	Compiler pass that splits ruleset nodes into multiple ruleset nodes by selector and declaration.
StrictCss2	This compiler pass enforces that only correct CSS 2.1 is used.
StrictCss3	This compiler pass enforces that only correct CSS level 3 is used.
StrictCssBase	Base class for compiler passes enforcing a specific CSS level.
TemplateCompactPrinter<T>	Printer for templates, which outputs GSS with holes to be filled for references.

UniformVisitor.Adapters	Adapter methods that transform UniformVisitors into CssTreeVisitors.
UnrollLoops	A compiler pass that unrolls loops.
UnsafeMergeRulesetNodes	Compiler pass that merges rulesets aggressively.
ValidatePropertyValues	A compiler pass that validates values of properties.
VerifyRecognizedProperties	CSS Compiler pass that checks that all properties in the stylesheet are either on the built-in recognized property list, or were whitelisted explicitly.
WarnOnCustomProperty	A compiler pass that warns when custom properties declarations and references are encountered, since they are not yet supported by all the major browsers.
