  • Constructor Details

    • UriExpression

      public UriExpression(String schema)
      Creates a new blank expression in the given schema.

      This constructor is mostly intended for internal use. Client code is expected to obtain a UriExpression object by parsing a string using parse(String, PrefixManager).

      Parameters:
      schema - The schema this expression conforms to.

  • Method Details

    • getSchema

      public String getSchema()
      Gets the schema part of this expression.
      Returns:
      The schema.

    • putComponent

      public void putComponent(String key, String value)
      Inserts a new component into this expression.

      This is mostly intended for internal use. Client code should refrain from modifying a URI Expression after it has been parsed.

      Parameters:
      key - The name of the slot.
      value - The value of the slot.

    • getComponent

      public String getComponent(String key)
      Gets the value of the given slot in this expression.
      Parameters:
      key - The name of the slot to retrieve.
      Returns:
      The value associated with that slot, or null if the expression has no such slot.

    • getComponentNames

      public Set<String> getComponentNames()
      Gets the name of all slots present in this expression.
      Returns:
      The slot names.

    • toURI

      public String toURI(PrefixManager prefixManager)
      Turns this object back to a string representation.
      Parameters:
      prefixManager - The prefix manager to use for condensing slot values into CURIEs.
      Returns:
      A string containing the encoded expression.

    • parse

      public static UriExpression parse(String uri, PrefixManager prefixManager)
      Parses a string into a URI Expression object.
      Parameters:
      uri - The string to parse.
      prefixManager - The prefix manager to use to expand CURIEs found within the expression.
      Returns:
      The parsed expression, or null if the string does not contain a valid URI Expression.
