Constructor Details

DefaultExpressionParserEngine

public DefaultExpressionParserEngine(List<TokenReader> tokenReaders,
 com.google.common.collect.ImmutableMap<Token,Operator> operators,
 com.google.common.collect.ImmutableList<ValueReader> valueReaders)

Creates a new instance of this class.
The provided TokenReader list will be used to create a new ExpressionTokenizer while the provided Map of Tokens and Operators and the List of ValueReaders will be used to create a new ExpressionTemplateParser.

Parameters:

tokenReaders - List of TokenReaders to use.

operators - Immutable Map of Token-Operator pairs to use.

valueReaders - Immutable List of ValueReaders to use.

Method Details

createDefault

public static DefaultExpressionParserEngine createDefault()

Convenience method to create a new instance of this class with default values already applied.
Calling this method is equal to calling new DefaultBuilder().addDefaults() followed by DefaultExpressionParserEngine.DefaultBuilder.build().

Returns:

A new DefaultExpressionParserEngine with all values already applied.

compile

public ExpressionTemplate compile(String text,
 ParseWarnCollector collector)

Parses the provided text into a ExpressionTemplate to use.

Specified by:

compile in interface ExpressionParserEngine

Parameters:

text - The text to parse into a ExpressionTemplate.

collector - ParseWarnCollector instance used to collect warnings during the parsing.

Returns:

New ExpressionTemplate to use.
