## [Java] Class GStringImpl

- org.codehaus.groovy.runtime.GStringImpl

-     public class GStringImpl
      extends GString

  Default implementation of a GString used by the compiler. A GString consists of a list of values and strings which can be combined to create a new String.

- - ### Constructor Detail

    - #### public GStringImpl(Object[] values, String[] strings)

      Create a new GString with values and strings.

      Each value is prefixed by a string, after the last value an additional String might be used, hence the following constraint is expected to hold: `strings.length == values.length || strings.length == values.length + 1` .

      NOTE: The lengths are not checked but using arrays with lengths which violate the above constraint could result in unpredictable behaviour.

      Parameters:
        `values` - the value parts
        `strings` - the string parts

    - #### protected GStringImpl(Object[] values, String[] strings, boolean cacheable, String cachedStringLiteral, boolean frozen)

      Create a new GString with values and strings.

      Each value is prefixed by a string, after the last value an additional String might be used, hence the following constraint is expected to hold: `strings.length == values.length || strings.length == values.length + 1` .

      NOTE: The lengths are not checked but using arrays with lengths which violate the above constraint could result in unpredictable behaviour.

      Parameters:
        `values` - the value parts
        `strings` - the string parts
        `frozen` - creates a GStringImpl which is not subject to mutation and hence more amenable to caching

      Get the strings of this GString.

      This method returns the same array as used in the constructor. Changing the values will result in changes of the GString. It is generally not recommended to do so.
