Method Detail
-
getInstance
public static JavaPlatform getInstance()
-
initialize
public void initialize(Configuration config)
Perform platform-specific initialization of the configuration- Specified by:
initialize
in interfacePlatform
-
makeAbsolute
public java.net.URI makeAbsolute(java.lang.String relativeURI, java.lang.String base) throws java.net.URISyntaxException
Construct an absolute URI from a relative URI and a base URI- Specified by:
makeAbsolute
in interfacePlatform
- Parameters:
relativeURI
- the relative URIbase
- the base URI- Returns:
- the absolutized URI
- Throws:
java.net.URISyntaxException
-
escapeSpaces
public static java.lang.String escapeSpaces(java.lang.String s)
Replace spaces by %20
-
tryToExpand
public static java.lang.String tryToExpand(java.lang.String systemId)
If a system ID can't be parsed as a URL, we'll try to expand it as a relative URI using the current directory as the base URI: MHK addition.
-
getPlatformVersion
public java.lang.String getPlatformVersion()
Get the platform version- Specified by:
getPlatformVersion
in interfacePlatform
-
getPlatformSuffix
public java.lang.String getPlatformSuffix()
Get a suffix letter to add to the Saxon version number to identify the platform- Specified by:
getPlatformSuffix
in interfacePlatform
-
getParserSource
public javax.xml.transform.Source getParserSource(javax.xml.transform.stream.StreamSource input, int validation, boolean dtdValidation, int stripspace)
Convert a StreamSource to either a SAXSource or a PullSource, depending on the native parser of the selected platform- Specified by:
getParserSource
in interfacePlatform
- Parameters:
input
- the supplied StreamSourcevalidation
-dtdValidation
-stripspace
-- Returns:
- the PullSource or SAXSource, initialized with a suitable parser, or the original input Source, if now special handling is required or possible. This implementation always returns the original input unchanged.
-
compileRegularExpression
public RegularExpression compileRegularExpression(java.lang.CharSequence regex, boolean isXPath, java.lang.CharSequence flags) throws XPathException
Create a compiled regular expression- Specified by:
compileRegularExpression
in interfacePlatform
- Parameters:
regex
- the source text of the regular expression, in XML Schema or XPath syntaxisXPath
- set to true if this is an XPath regular expression, false if it is XML Schemaflags
- the flags argument as supplied to functions such as fn:matches(), in string form- Returns:
- the compiled regular expression
- Throws:
XPathException
- if the syntax of the regular expression or flags is incorrect
-
makeCollation
public java.util.Comparator makeCollation(Configuration config, java.util.Properties props) throws XPathException
Obtain a collation with a given set of properties. The set of properties is extensible and variable across platforms. Common properties with example values include lang=ed-GB, strength=primary, case-order=upper-first, ignore-modifiers=yes, alphanumeric=yes. Properties that are not supported are generally ignored; however some errors, such as failing to load a requested class, are fatal.- Specified by:
makeCollation
in interfacePlatform
- Parameters:
config
- the configuration objectprops
- the desired properties of the collation- Returns:
- a collation with these properties
- Throws:
XPathException
- if a fatal error occurs
-
canReturnCollationKeys
public boolean canReturnCollationKeys(java.util.Comparator collation)
Given a collation, determine whether it is capable of returning collation keys. The essential property of collation keys is that if two values are equal under the collation, then the collation keys are equal under the equals() method.- Specified by:
canReturnCollationKeys
in interfacePlatform
- Parameters:
collation
- the collation, provided as a Comparator- Returns:
- true if this collation can supply collation keys
-
getCollationKey
public java.lang.Object getCollationKey(java.util.Comparator collation, java.lang.String value)
Given a collation, get a collation key. The essential property of collation keys is that if two values are equal under the collation, then the collation keys are compare correctly under the compareTo method.- Specified by:
getCollationKey
in interfacePlatform
- Returns:
- a representation of the collation key, such that two collation keys are equal() if and only if the string values they represent are equal under the specified collation.
- Throws:
java.lang.ClassCastException
- if the collation is not one that is capable of supplying collation keys (this should have been checked in advance)
-
addFunctionLibraries
public void addFunctionLibraries(FunctionLibraryList list, Configuration config)
Add platform-specific function libraries to the function library list- Specified by:
addFunctionLibraries
in interfacePlatform
-
getExternalObjectType
public SchemaType getExternalObjectType(java.lang.String uri, java.lang.String localName)
- Specified by:
getExternalObjectType
in interfacePlatform
