## Interface FieldReferenceConverter.Delegate

- All Known Implementing Classes:
    StrictAttributeParser.FieldReferenceDelegate, StringAttributeParser.FieldReferenceDelegate
  Enclosing class:
    FieldReferenceConverter

      static interface FieldReferenceConverter.Delegate

  Responsible for the bits around and between the field references. May throw IllegalFieldReferenceException as it sees fit.

- - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `JType[]` | `getTypes()` Returns the types any parsed field references are expected to return.
    `java.lang.String` | `handleFragment(java.lang.String fragment)` Called for fragment around and between field references.
    `java.lang.String` | `handleReference(java.lang.String reference)` Called for each expanded field reference, to allow it to be stitched together with surrounding fragments.

- - ### Method Detail

    - #### getTypes

          JType[] getTypes()

      Returns the types any parsed field references are expected to return. Multiple values indicates an overload. E.g., in either a String or a SafeUri is allowed.

    - #### handleFragment

          java.lang.String handleFragment(java.lang.String fragment)
                                          throws FieldReferenceConverter.IllegalFieldReferenceException

      Called for fragment around and between field references.

      Note that it will be called with empty strings if these surrounding bits are empty. E.g., "{style.enabled} fancy {style.impressive}" would call this method three times, with "", " fancy ", and "".

      A string with no field references is treated as a single fragment, and causes a single call to this method.

      Throws:
        `FieldReferenceConverter.IllegalFieldReferenceException`

    - #### handleReference

          java.lang.String handleReference(java.lang.String reference)
                                           throws FieldReferenceConverter.IllegalFieldReferenceException

      Called for each expanded field reference, to allow it to be stitched together with surrounding fragments.
      Throws:
        `FieldReferenceConverter.IllegalFieldReferenceException`
