AjxUtil

AjxUtil()

AjxUtil - static class with some utility methods. This is where to put things when no other class wants them. 12/3/2004 At this point, it only needs AjxEnv to be loaded.

assert

<static> void assert(aCondition, aMessage)

collapseList

<static> Object collapseList(list)

Returns a copy of a list with empty members removed.

Parameters:
list - [array] original list

createProxy

<static> Object createProxy(object, level)

This method returns a proxy for the specified object. This is useful when you want to modify properties of an object and want to keep those values separate from the values in the original object. You can then iterate over the proxy's properties and use the hasOwnProperty method to determine if the property is a new value in the proxy.

Note: A reference to the original object is stored in the proxy as the "_object_" property.

Parameters:
object - [object] The object to proxy.
level - [number] The number of property levels deep to proxy. Defaults to zero.

formatSize

<static> Object formatSize(size, round, fractions)

Formats a size (in bytes) to the largest whole unit. For example, AjxUtil.formatSize(302132199) returns "288 MB".

Parameters:
size - The size (in bytes) to be formatted.
round - True to round to nearest integer. Default is true.
fractions - Number of fractional digits to display, if not rounding. Trailing zeros after the decimal point are trimmed.

formatSizeForUnits

<static> Object formatSizeForUnits(size, units, round, fractions)

Formats a size (in bytes) to a specific unit. Since the unit size is known, the unit is not shown in the returned string. For example, AjxUtil.formatSizeForUnit(302132199, AjxUtil.SIZE_MEGABYTES, false, 2) returns "288.13".

Parameters:
size - The size (in bytes) to be formatted.
units - The unit of measure.
round - True to round to nearest integer. Default is true.
fractions - Number of fractional digits to display, if not rounding. Trailing zeros after the decimal point are trimmed.

onassert

<static> void onassert(aMessage)

parseSize

<static> Object parseSize(formattedSize, units)

Performs the opposite of AjxUtil.formatSize in that this function takes a formatted size.

Parameters:
units - Unit constant: "GB", "MB", "KB", "B". Must be specified unless the formatted size ends with the size marker, in which case the size marker in the formattedSize param overrides this parameter.

xmlToJs

<static> Object xmlToJs(node, omitName)

Convert an XML node to the equivalent JS. Traverses the node's children recursively.

NOTE: This method has not been extensively tested and likely needs work.

Parameters:
node - [Element] XML node
omitName - [boolean] if true, don't include node name in output
