public PropertyReplacers()

Method Detail

noop

public static PropertyReplacer noop()

Return a replacer that functions as a no-op.

Returns:

the replacer. Will not be null

resolvingReplacer

@Deprecated
public static PropertyReplacer resolvingReplacer(PropertyResolver resolver)

Deprecated. use resolvingExpressionReplacer(SimpleExpressionResolver)

Return a PropertyReplacer that uses the provided PropertyResolver to resolve any properties found in the text. The returned replacer searches for strings beginning with the string "${" and ending with the char '}', and passes the value within to the given resolver. The replacer supports arbitrarily nested expressions, finding the inner-most expressions and resolving those before using the resolved values to compose the outer expressions. The replacer also supports recursive resolution, so if a resolved value is itself in the form of an expression, that expression will in turn be resolved.

Parameters:

resolver - the resolver used for any properties being replaced. Cannot be null

Returns:

the replacer. Will not be null

resolvingExpressionReplacer

public static PropertyReplacer resolvingExpressionReplacer(SimpleExpressionResolver resolver)

Return a PropertyReplacer that uses the provided SimpleExpressionResolver to resolve any expressions found in the text. The returned replacer searches for strings beginning with the string "${" and ending with the char '}', and passes the value within to the given resolver. The replacer supports arbitrarily nested expressions, finding the inner-most expressions and resolving those before using the resolved values to compose the outer expressions. The replacer also supports recursive resolution, so if a resolved value is itself in the form of an expression, that expression will in turn be resolved.

Parameters:

resolver - The resolver used for any expressions being replaced. Cannot be null

Returns:

the replacer. Will not be null
