Example 1 with InterpolatorElement

use of org.jetbrains.android.dom.animation.InterpolatorElement in project android by JetBrains.

the class AttributeProcessingUtil method processAttributes.

/**
   * Enumerate attributes that are available for the given XML tag, represented by {@link AndroidDomElement},
   * and "return" them via {@link AttributeProcessor}.
   *
   * Primary user is {@link AndroidDomExtender}, which uses it to provide code completion facilities when
   * editing XML files in text editor.
   *
   * Implementation of the method implements {@link Styleable} annotation handling and dispatches on tag type
   * using instanceof checks for adding attributes that don't come from styleable definitions with statically
   * known names.
   *
   * @param processAllExistingAttrsFirst whether already existing attributes should be returned first
