  • Method Details

    • getFields

      Field[] getFields()

    • setFields

      void setFields​(Field[] fields)

    • buildIndexMapping

      void buildIndexMapping()
      Builds a hash between column names and their indices for fast retrieval. This is done lazily to support findColumn() and get*(String), as it can be more expensive than just retrieving result set values by ordinal index.

    • hasBuiltIndexMapping

      boolean hasBuiltIndexMapping()

    • getColumnLabelToIndex

      java.util.Map<java.lang.String,​java.lang.Integer> getColumnLabelToIndex()

    • setColumnLabelToIndex

      void setColumnLabelToIndex​(java.util.Map<java.lang.String,​java.lang.Integer> columnLabelToIndex)

    • getFullColumnNameToIndex

      java.util.Map<java.lang.String,​java.lang.Integer> getFullColumnNameToIndex()

    • setFullColumnNameToIndex

      void setFullColumnNameToIndex​(java.util.Map<java.lang.String,​java.lang.Integer> fullColNameToIndex)

    • getColumnNameToIndex

      java.util.Map<java.lang.String,​java.lang.Integer> getColumnNameToIndex()

    • setColumnNameToIndex

      void setColumnNameToIndex​(java.util.Map<java.lang.String,​java.lang.Integer> colNameToIndex)

    • getColumnToIndexCache

      java.util.Map<java.lang.String,​java.lang.Integer> getColumnToIndexCache()

    • setColumnToIndexCache

      void setColumnToIndexCache​(java.util.Map<java.lang.String,​java.lang.Integer> columnToIndexCache)

    • initializeFrom

      void initializeFrom​(ColumnDefinition columnDefinition)

    • exportTo

      void exportTo​(ColumnDefinition columnDefinition)

    • findColumn

      int findColumn​(java.lang.String columnName, boolean useColumnNamesInFindColumn, int indexBase)

    • hasLargeFields

      boolean hasLargeFields()
      Check if fields with type BLOB, MEDIUMBLOB, LONGBLOB, TEXT, MEDIUMTEXT or LONGTEXT exist in this ColumnDefinition.
      Returns:
      true if fields with type BLOB, MEDIUMBLOB, LONGBLOB, TEXT, MEDIUMTEXT or LONGTEXT exist in this ColumnDefinition.
