CategoryPath(String[])

Construct from the given path components.

Declaration

Declaration
public static readonly CategoryPath EMPTY
Field Value
Type Description
CategoryPath

Components

The components of this CategoryPath. Note that this array may be shared with other CategoryPath instances, e.g. as a result of Subpath(Int32), therefore you should traverse the array up to Length for this path's components.

Declaration
public string[] Components { get; }
Property Value
Type Description
System.String[]

Length

The number of components of this CategoryPath.

Declaration
public int Length { get; }
Property Value
Type Description
System.Int32

Methods

CompareTo(CategoryPath)

Compares this path with another CategoryPath for lexicographic order.

Declaration
public virtual int CompareTo(CategoryPath other)
Parameters
Type Name Description
CategoryPath other
Returns
Type Description
System.Int32

CopyFullPath(Char[], Int32, Char)

Copies the path components to the given char[], starting at index start. delimiter is copied between the path components. Returns the number of chars copied.

NOTE: this method relies on the array being large enough to hold the components and separators - the amount of needed space can be calculated with FullPathLength().

Declaration
public virtual int CopyFullPath(char[] buf, int start, char delimiter)
Parameters
Type Name Description
System.Char[] buf
System.Int32 start
System.Char delimiter
Returns
Type Description
System.Int32

Equals(Object)

Parameters
Type Name Description
System.Object obj
Returns
Type Description
System.Boolean

FullPathLength()

Returns the number of characters needed to represent the path, including delimiter characters, for using with CopyFullPath(Char[], Int32, Char).

Declaration
public virtual int FullPathLength()
Returns
Type Description
System.Int32

GetHashCode()

Declaration
public override int GetHashCode()
Returns

Int64HashCode()

Calculate a 64-bit hash function for this path.

NOTE: This was longHashCode() in Lucene

Declaration
public virtual long Int64HashCode()

CategoryPath
