Method Detail

setXMLEntityExpansionLimit

public static void setXMLEntityExpansionLimit(int nEntityExpansionLimit)

Limit the number of entity expansions.
This setting only takes effect if a parser with explicitly disabled "Secure processing" feature is used. Otherwise this setting has no effect!

Parameters:

nEntityExpansionLimit - A positive integer. Values ≤ 0 are treated as no limit.

setXMLEntityExpansionLimit

public static void setXMLEntityExpansionLimit(@Nullable
                                              String sEntityExpansionLimit)

Limit the number of entity expansions.
This setting only takes effect if a parser with explicitly disabled "Secure processing" feature is used. Otherwise this setting has no effect!

Parameters:

sEntityExpansionLimit - A positive integer as a String. Values ≤ 0 are treated as no limit. null means the property is deleted

getXMLEntityExpansionLimit

public static int getXMLEntityExpansionLimit()

setXMLElementAttributeLimit

public static void setXMLElementAttributeLimit(int nElementAttributeLimit)

Limit the number of attributes an element can have.
This setting only takes effect if a parser with explicitly disabled "Secure processing" feature is used. Otherwise this setting has no effect!

Parameters:

nElementAttributeLimit - A positive integer. Values ≥ 0 are treated as no limit.

getXMLElementAttributeLimit

public static int getXMLElementAttributeLimit()

setXMLMaxOccur

public static void setXMLMaxOccur(int nMaxOccur)

Limit the number of content model nodes that may be created when building a grammar for a W3C XML Schema that contains maxOccurs attributes with values other than "unbounded".
This setting only takes effect if a parser with explicitly disabled "Secure processing" feature is used. Otherwise this setting has no effect!

Parameters:

nMaxOccur - A positive integer. Values ≥ 0 are treated as no limit.

getXMLMaxOccur

public static int getXMLMaxOccur()

setXMLTotalEntitySizeLimit

public static void setXMLTotalEntitySizeLimit(int nTotalEntitySizeLimit)

Limit the total size of all entities that include general and parameter entities. The size is calculated as an aggregation of all entities.
This is available since JDK 1.7.0_45/1.8.
This setting only takes effect if a parser with explicitly disabled "Secure processing" feature is used. Otherwise this setting has no effect!

Parameters:

nTotalEntitySizeLimit - A positive integer. Values ≥ 0 are treated as no limit.

getXMLTotalEntitySizeLimit

public static int getXMLTotalEntitySizeLimit()

setXMLMaxGeneralEntitySizeLimit

public static void setXMLMaxGeneralEntitySizeLimit(int nMaxGeneralEntitySizeLimit)

Limit the maximum size of any general entities. It is recommended that users set the limit to the smallest possible number so that malformed xml files can be caught quickly.
This is available since JDK 1.7.0_45/1.8.
This setting only takes effect if a parser with explicitly disabled "Secure processing" feature is used. Otherwise this setting has no effect!

Parameters:

nMaxGeneralEntitySizeLimit - A positive integer. Values ≥ 0 are treated as no limit.

getXMLMaxGeneralEntitySizeLimit

public static int getXMLMaxGeneralEntitySizeLimit()

setXMLMaxParameterEntitySizeLimit

public static void setXMLMaxParameterEntitySizeLimit(int nMaxParameterEntitySizeLimit)

Limit the maximum size of any parameter entities, including the result of nesting multiple parameter entities. It is recommended that users set the limit to the smallest possible number so that malformed xml files can be caught quickly.
This is available since JDK 1.7.0_45/1.8.
This setting only takes effect if a parser with explicitly disabled "Secure processing" feature is used. Otherwise this setting has no effect!

Parameters:

nMaxParameterEntitySizeLimit - A positive integer. Values ≥ 0 are treated as no limit.

getXMLMaxParameterEntitySizeLimit

public static int getXMLMaxParameterEntitySizeLimit()
